Anxiety builds up!

While laying on my bed thinking about my future, I can’t stop the anxiety that’s wandering inside of me. Im a little excited about what’s in store but ended up being uneasy about it. I have lots of dreams on my mind. Example would be I wanted to be a doctor (actually until now), but my mother ended this desire the moment I handed her my diploma from my bachelors degree. She told me that I better have my masters parallel to what I had finished for me to be able to have a great job offered on our field, and after coming on that thought, I think she’s right. Even though my dream on becoming a doctor isn’t already sensible (financial crisis daw. Haha.) my dream of being a successful R-ND is still at hand. (Having a job that gives me the satisfaction, more knowledgeable on my field and syempre a stable job.) So to follow what she had said I started inquiring to the different universities here in the country. But after reading some of the requirements from the Univs where I made inquiries, I came to realized that graduate school isn’t as ordinary as college life. You should be mature enough (both mentally and emotionally) before attending the school. Besides at graduate school, I’ll be dealing with different people and more often, older than me. And this fact gave me the call that I am not ready to enter school again yet. And this point troubles me. My first step to attain my goal isn’t laid out. What should I do?? I’m really stuck with the job that I have right now. But I think I need to have the "more experience" to have that “maturity” I’m looking for.. I really want to work in a hospital. Much of my knowledge is in clinical setting. But I still haven’t had the opportunity to work at any institution.. I’m so damn stuck here. Dreaming to have a perfect life with the perfect job. I know I’m still young for me to attain success with my profession. (young pa ba ang 21) but It seems like my ambition is running away from me, and its really nerve-wracking!
